Power Management Tools - Solid State Logic ORIGIN User Manual

For the METERS section, the Secondary functions are identified by a white outline
around the switch label, such as the DIM MIX METERS function. Pressing SHIFT
and the respective switch simultaneously activates the secondary function.
CLEAR ROUTE
The SHIFT switch also has some interaction with the Track Bus Routing functions.
When a channel or a bus is in Route Select mode (flashing blue LED) pressing
SHIFT will escape back to the normal console state. i.e. it acts to cancel/clear
Route Select function.
If SHIFT is pressed and held down and a ROUTE switch selected, either in a
Channel, Stereo Return or in the the Buses section, then routes to and/or from the
selected path will be cleared. (see Appendix A)

Power Management Tools

ORIGIN is designed with some clever and useful tools to help manage the power requirements of the console. Older analogue
consoles (and other studio devices) typically don't like being switched on and off. This is partly because of the heat/cool cycles
causing issues with components such as valves(tubes), transformers, relays and capacitors. Additionally because of the electrical
stresses caused by inrush currents when large linear power supplies are switched on. For these reasons, many older studio
consoles are left on 24 hours a day with the associated cooling/air conditioning plant also running at the same time. ORIGIN's
circuitry and power supplies are designed to be powered on and off under the control of the console's Power Management Tools.
This allows the console to be regularly powered on and off without issue and hence we have provided a WAKE/SLEEP switch and
an AUTO SLEEP function to provide a timed power down along with simple switches for this useful feature.
AUTO SLEEP and WAKE/SLEEP
Origin can be put into Sleep mode by pressing and holding the WAKE/SLEEP switch for approximately 3 seconds. When the
console is in Sleep mode, the WAKE/SLEEP LED will pulse smoothly at about 1 pulse per second. The console can be awoken
from Sleep by pressing the WAKE/SLEEP switch.
When the console enters 'Sleep' mode it carries out a controlled power down sequence. The Monitor Output Relays disconnect
the Monitor Loudspeakers, next the Master Section powers down with a controlled shutdown of the power rails, shortly followed by
the power rails for the console channels. Similarly when waking, the power up sequence is controlled. This means that monitors
left powered and connected are not affected by loud thumps caused by sudden circuit activation in the console.
The AUTO SLEEP switch enables the Auto Sleep function which monitors meter activity. If no activity is detected over a preset
amount of time (15 seconds to 75 minutes, see Appendix B - Setup Functions), the console automatically enters Sleep mode. As
above, when the console is in Sleep mode, the WAKE/SLEEP LED pulses smoothly at about 1 pulse per second and the console
can be awoken from Sleep by pressing the WAKE/SLEEP switch. Approximately 60 seconds before the Sleep mode is activated
the WAKE/SLEEP LED flashes quickly to indicate the console is about to go to sleep.
How it works - The console detects activity on any of the LED meters and/or the Routing/Talkback/Comms/Meter
switch functions to detect the console is in use. If no activity is detected for a preset period, the console can enter
a 'Sleep' state, where the bare minumum of circuitry is powered and the console is ready at any moment to Wake to
its pre-sleep state. When in Sleep mode ORIGIN consumes approximately 4% of the power needed in its wake state
(approximately 40 W in sleep state and <1 kW in its wake state).
